6. CONFIGURATION
6.1 INPUT SELECTION / MEASURING SCALE
You can select the type of input by setting SW1 DIP switches placed on the side of the module.
Every type of input is matched to a certain number of beginning and end scale values which can be
selected through SW2 DIP switches.
The following table lists possible START and END values according to the type of input selected.
The left column show the DIP-switches setting in order to select the START and END scale desired.

6.4 CONFIGURATION THROUGH A PC
By using a PC and EASY SETUP software, it is possible to set: input type, input start and end of scale,
measurement type, rejection filter, resolution, output signal, output start and end of scale, conversion value,
upper and lower limits, output value if there is an error and digital output filter.
The instrument is factory set for a 3 wires temperature measurement, however it’s possible to select a 2
or 4 wires reading by reprogramming the module.
The START and END push-buttons under the SW2 DIP-switch group allow to set the beginning and end
scale at will, within the scale pre-set through the dip-switches. To obtain this facility it is necessary to use
a suitable signal generator, able to furnish the desidered values of beginning and end scale.
The procedure is following:
1. Set through dip-switches the type of input, START and END measurement which include the required
beginning and end values.
2. Power up the module.
3. Supply a calibrator or simulator of the signal you wish to measure and re-transmit.
4. Set the required START value on the calibrator (or other instrument).
5. Press the START push-button for at least 3 sec. The green LED on the front panel flashes to indicate
the value has been stored.
6. Repeat points 4 and 5 for the required END value.
7. Power off the module and set to OFF position the dip-switches of group SW2, correspondent to the
settings of START and END values.
The module is now configured for the required start and end scale.
In order to re-program it (e.g. for a different type of input) repeat the whole procedure.
6.2 START AND END SETTING AT WILL
SW2 group DIP-switches 7 and 8 enable you to set the output with or without zero elevation and/or
as a normal or reversed output. The SW3 DIP-switch group enables you to select the output type.
Note:The DIP-switches must be set while the module is powered down, avoiding electrostatic
discharge, otherwise the module may be damaged.
